Apparatus and method for transmitting and receiving packets in a mobile communication system supporting hybrid automatic repeat request

A method for operating Hybrid Automatic Repeat reQuest (HARQ) in a mobile communication system, the method comprising:

• transmitting a number of HARQ processes of a persistent resource allocation and persistent resource allocation interval information;
• transmitting data according to the persistent resource allocation interval information;
• calculating a HARQ process IDentifier (ID) using the number of HARQ processes of the persistent resource allocation, the persistent resource allocation interval information, and time information;
• and
• associating a HARQ process with the calculated HARQ process ID.

An apparatus for operating Hybrid Automatic Repeat reQuest (HARQ) in a communication system, the apparatus comprising:

• a receiver that receives a number of HARQ processes of a persistent resource allocation and persistent resource allocation interval information, and receives data according to the persistent resource allocation interval information;
• a controller that calculates a HARQ process IDentifier (ID) using the number of HARQ processes of the persistent resource allocation, the persistent resource allocation interval information, and time information, and associating a HARQ process with the calculated HARQ process ID;
• and
• a HARQ processor that performs a HARQ operation for the received data.
